Abstract: A vehicle driveline component with a ball-ramp mechanism that includes a first ball-ramp ring, a second ball-ramp ring and a plurality of balls. Each of the first and second ball-ramp rings have a plurality of ball supports that define ball tracks that receive the balls. Each of the ball supports has a first radial width at a first location and a second radial width at a second location. The first and second widths are different to minimize the amount of material that forms the first and second ball-ramp rings.

Abstract: An electrically-operated electric drive module for use in a vehicle framework that is configured for a powertrain that includes an internal combustion engine. The electrically-operated electric drive module permits the vehicle to be converted to an electrically propelled vehicle in a manner that is cost-effective and which is relatively low in weight.

Abstract: An electric drive unit that includes an electric motor having a rotor with a rotor shaft and a heat exchanger that is received in the rotor shaft. The heat exchanger has a plurality of heat exchanger plates, each of which having a hub, a rim member, and disc spring portion that interconnects the hub and the rib member. Each disk spring portion defines a plurality of coolant apertures. The heat exchanger plates are press-fit to the rotor shaft such that each disc spring portion is deflected from a pre-installation state, and each rim member is engaged to an interior surface of the rotor shaft while being spaced apart from adjacent rim members along a rotational axis of the rotor. A first coolant passage is disposed through the hubs of the plates. The coolant apertures in the heat exchanger plates cooperate to form a plurality of second coolant passages.

Abstract: A front axle assembly with an axle housing that has first and second housing halves that each include a main housing portion, a tubular portion and a steering yoke. The main housing portion defines a cavity that houses at least a portion of a speed differentiation mechanism. The tubular portions are fixedly coupled to an associated one of the main housing portions and extend between the main housing portion and an associated one of the steering yokes. Each steering yoke is fixedly coupled to an associated tubular portion. An annular joint structure is formed where the first and second first housing halves are coupled to one another. The annular joint structure is formed about the rotary axis such that one of the first and second housing halves is inserted into the other one of the first and second housing halves along an insertion axis that is coincident with the rotary axis.

Abstract: A differential assembly that includes a differential input member, a differential gear set, a first clutch, and a second clutch. The differential input member is rotatable about a differential axis and defines an internal cavity. The differential gear set is received in the differential cavity and includes first and second side gears. The first clutch has a plurality of first clutch plates and a plurality of second clutch plates. The first clutch plates are rotatably coupled to the differential input member. The second clutch plates are interleaved with the first clutch plates and are rotatably coupled to the first side gear. The second clutch is selectively operable to non-rotatably couple one of the first and second side gears to the differential input member.

Abstract: A disconnectable vehicle driveline having front and rear axle assemblies and a power take-off unit (PTU). The PTU includes a coupling, which is configured to selectively transmitting rotary power between an input shaft and a first gear, and a brake element. The coupling includes a first coupling portion, which is coupled to the input shaft for rotation therewith, and a second coupling portion that is coupled to the first gear for common rotation. The second coupling portion can be translated into and out of engagement with the first coupling portion. The brake element is configured to engage the second coupling portion when the second coupling portion is not engaged to the first coupling portion to thereby resist rotation of the first gear and elements of the vehicle driveline that are drivingly coupled to the first gear.

The first sleeve has a first externally toothed body, a first flange, which extends radially outwardly from the first body, and a first bore. The barrel is received in the first bore and is rotatable therein. The follower is fixed to one of the barrel and the first sleeve and is received in the groove, which is formed in the other one of the barrel and the first sleeve. The second sleeve has a second body with an internally toothed second bore. The second sleeve is disposed about the first sleeve such that internal and external teeth are meshed to axially slidably but non-rotatably couple the first and second sleeves. The spring is disposed between the first flange and the second sleeve.
